Only a gale-force upset could blow Real Madrid off course for a spot in the Copa del Rey (Spanish Cup) quarterfinals.

Real Madrid will visit Sevilla on Thursday at Ramon Sanchez Pizjuan Stadium in the second leg of its Copa del Rey round of 16 series. Real Madrid enters the contest with a 3-0 lead, courtesy of its first-leg win on Jan. 4.

A Real Madrid win or draw would extend the club’s unbeaten streak to 40 games, setting a new Spanish record in the process.
